Munetaka Murakami hit his 30th home run on September 5, 2026 — a first-inning shot to left field off Tampa Bay’s Taj Bradley at Rate Field — and became the first Japanese-born player in MLB history to hit 30 home runs as a rookie. The record is precise, and it matters: Hideki Matsui hit 31 HR in 2004, but that was already his second season. Shohei Ohtani surpassed that number too, but never in his debut year. Murakami got there where no one else had.
74 Plate Appearances Without a Homer — and It Still Didn’t Shake Him
The milestone didn’t come easily. Murakami had gone 74 plate appearances without a home run since August 18 — a drought that in most situations would’ve set off alarms. But context is everything: his OBP held in useful territory during that stretch, boosted by his 81 walks on the season, and his Statcast profile didn’t budge. The hitter was the same. The ball just wasn’t falling.
September 5 changed that. The homer came in the first inning against a pitcher who had no reason to give him anything easy. It was also the 10th game in 2026 in which Murakami and Colson Montgomery both went deep on the same day — a mark that, according to MLB.com, ties a historical record for a White Sox duo.
What Matsui and Ohtani Never Did in Year One
To understand the scope of this, the categories have to be kept separate. Matsui’s 31-HR season came in 2004, his second year in the majors. Ohtani topped that total multiple times, but also not in his debut. Murakami did it in his first: he made his MLB debut on March 26, 2026, and signaled immediately what was coming — a home run with a 103.0 mph exit velocity, a 31-degree launch angle, and 383 feet of distance off a 90.5 mph cutter.
Murakami arrived at the White Sox with a résumé built over eight NPB seasons with the Tokyo Yakult Swallows: 246 career home runs, the Japanese league record of 56 HR in 2022, and the youngest Triple Crown winner in Japanese professional baseball history. He signed a two-year, $34 million deal — well below the $80 million projections some analysts had floated — after teams including the Mets, Red Sox, Angels, and Diamondbacks passed on him.
Manager Will Venable wasn’t surprised by any of it. After Murakami’s first home run at Rate Field in April, Venable told reporters, as quoted by MLB.com: «He’s been everything we imagined in terms of his impact in the clubhouse, who he is as a person, his defensive play, as well as the power and discipline at the plate.»
Murakami, speaking through interpreter Kenzo Yagi on that same occasion, kept it simple: «It was always a dream for me to play here and hit in front of the fans at Rate Field. I just want to keep going through this process.»
Three Players With 30 HR — Only the Fourth Time in White Sox History
Murakami’s 30th home run also carried team weight. With that swing, the White Sox became one of only four versions of the franchise to have three players hit at least 30 home runs in the same season — Murakami, Colson Montgomery (who reached 30 the previous Friday), and Miguel Vargas. The other three times it happened: 2004, 2006, and 2008.
It’s the reflection of a season that looked impossible twelve months ago. Chicago enters the final 20 games of the year as a comfortable leader of the AL Central — a contender rebuilt, in large part, by a player who started contributing from Opening Day. Murakami was named to the 2026 All-Star Game, and the club is already exploring a contract extension.
The number that best explains why he works isn’t his batting average (.211), which a quick glance can easily misread. It’s the combination of discipline and raw power: Murakami carries a 93.9 mph average exit velocity and a 19.3% barrel rate — both ranking in the 98th and 100th percentile, respectively, among all MLB hitters in 2026. Very few people on the planet hit the ball that hard, that consistently.
The Numbers Behind the Record
Here’s what Statcast has on Murakami through the 2026 season:
- 464 plate appearances
- 30 home runs, 61 RBI
- AVG: .211
- OPS: .827
- xwOBA: .352 (what quality of contact says he should be producing)
- Average exit velocity: 93.9 mph
- Barrel rate: 19.3%
- Hard-hit rate: 57% (balls hit 95 mph or harder)
- Average bat speed: 74.8 mph
How he ranks across MLB:
- xwOBA: 84th percentile
- Bat speed: 81st percentile
- Exit velocity: 98th percentile (elite)
- Barrel %: 100th percentile (elite)
- Hard-hit %: 99th percentile (elite)
- Squared-up rate: 10th percentile (one of the lowest in MLB)
- Chase rate: 90th percentile (elite)
- Whiff rate: 1st percentile (one of the lowest in MLB)
The .211 average will keep some people looking the other way. The barrel rate at the 100th percentile and an exit velocity in the 98th should bring them back.
